How Do Vegans Increase Iron Levels?
How Do Vegans Increase Iron Levels?
Iron is a mineral essential for proper growth and development. Your body uses it to make hemoglobin and certain hormones. Two types of iron are found in food: heme (animal-derived) and non-heme (plant-derived). Although it can be taken as a supplement, enough iron is available in our dietary sources. Vegans can find non-heme iron in dried beans and legumes, dark green leafy vegetables, dried fruits, nuts and seeds, and wholegrain cereals and bread.
Hemoglobin is a protein in red blood cells that carries oxygen from your lungs to all parts of the body. Myoglobin, another protein made by iron, brings oxygen to your muscles. Your body needs iron to function properly. Too little will lead to an iron deficiency. Too much can cause iron poisoning. The average amount of iron a vegan needs is 32 milligrams per day for women and 14 milligrams per day for men. Vegans need up to 1.8 times more iron than people who eat meat.
If you eat a vegan or vegetarian diet, or if you're just aiming to keep your iron levels up, you probably know some of the many vegetables, fruits and grains that are good sources of iron. But did you know that not all iron is the same and that some foods actually make it harder for your body to absorb iron? If this is news to you, the folks at Stanford Blood Center
have a how-to checklist that will help your body get the most iron out of your diet so you can stay healthy and have enough iron in reserve to donate blood to someone in need.
As the Stanford Blood Center blog explains, there are two types of iron: heme and non-heme. Heme iron is found in animal products and is generally easier for the body to absorb. Non-heme iron is found in vegan foods and is not as easily absorbed.
Iron deficiency anemia occurs when your body doesn't have enough iron to make hemoglobin — the part of red blood cells that bind and carry oxygen in your blood. As the blog explains, “a vegetarian or vegan diet can make it difficult to keep your iron levels high – but contrary to popular belief, this is because of the type of iron consumed, not simply the amount.”
Iron deficiency is the most common nutrient deficiency in the world. The good news is that you can get all the iron you need from a vegan diet because there are lots of plant foods containing good amounts of this mineral. In the UK, it is recommended that most adults have a dietary iron intake of 8.7mg (milligrams) per day. However, those who menstruate should aim for a higher intake of 14.8mg per day.
Good plant sources of iron include lentils, chickpeas, beans, tofu, cashew nuts, chia seeds, ground linseed, hemp seeds, pumpkin seeds, kale, dried apricots and figs, raisins, quinoa and fortified breakfast cereal. There are lots of factors that affect the amount of iron your body can absorb from your diet.
The most important factor is your body’s need for iron: more is absorbed when your body is short of iron, and less is absorbed when your stores are full. Tea, coffee and some substances in plant foods may make it difficult for your body to absorb iron. On the other hand, vitamin C increases iron absorption. Good sources of vitamin C include pepper, broccoli, cabbage, Brussels sprouts, kiwifruit, oranges, strawberries, pineapple, grapefruit and orange juice.
People give up eating meat and animal products such as milk, cheese, and eggs for many reasons. But doing so may increase the risk of iron deficiency anemia, a potentially serious condition in which the body does not make enough oxygen-bearing red blood cells.
For vegetarians who eliminate meat, anemia can be due to an iron deficiency. For vegans, who give up all animal products including dairy, eggs, and even honey, anemia can also be caused by vitamin B12 deficiency. The answer is to eat a carefully balanced diet — by getting needed iron and B12 from other sources, you should be able to stay committed to a vegetarian or vegan diet and prevent anemia.
What Is Iron?
Iron (Fe) is a nutrient present in the heme portion of iron-rich foods. This makes up approximately 30% of the iron in animal products and dietary supplements. Iron is essential for normal growth and development in children and adults. A deficiency in iron results in short stature and fatigue. Anemia, a condition in which your body does not produce enough red blood cells, also can be the result of inadequate iron intake.
Do vegans need as much iron as other people? Your body needs up to 1.8 times more iron than people who eat meat. Vegans need up to 1.8 times more iron than people who eat meat. It's always safe to take a vitamin B-12 supplement, but there's no evidence that it's necessary for vegans.
Iron is one of the main components of hemoglobin, a protein in red blood cells that transports oxygen to your muscles. Iron is critical to good health: it supports the cells that make your immune system, can keep a healthy level of iron in your blood, and is needed to build new blood cells.
Iron is essential for all of these processes, and although it’s found in most animals, it’s difficult for us to get enough in our diets. Maintain healthy levels of iron by eating plenty of iron-rich foods. Even though you may not think of eating beans as part of your daily meal, legumes are rich in iron. An ounce of cooked black beans (240 calories) provides 100 percent of your recommended daily amount of iron.
Why Do Vegans Need More Iron?
Protein shakes, frozen desserts, soda, beer, and red meat are protein-rich foods and will help meet your dietary needs. It’s important to be sure to get enough iron from your diet because iron can be stored, like fat, in your body. Stored iron is converted to toxic levels of iron-related compounds that can cause health problems. Nerve pain and muscle weakness are common symptoms of too much iron. How do I increase iron?
This may take several weeks to start seeing improvements. Symptoms of anemia (low red blood cell count) may include:
- Fatigue,
- Shortness of breath,
- Weakness and fatigue,
- Abdominal pain or discomfort,
- Irregular heartbeat, and
- Night sweats.
Fatigue occurs when you’re losing too many red blood cells because of a problem with blood flow (asthma, stroke, or heart disease).
A vegan diet is a complete one. You are consuming no animal products. Meat, fish, eggs, dairy and gelatin are all products of animals. Most vegans consume natural foods (vegetables, grains and legumes) and supplements, but this is not enough for optimal health. Vegan foods are often iron-deficient. All vegans are exposed to environmental pollutants and chemical substances.
These chemicals lead to an increased risk of infections, cancer, and weak bones. Iron-deficient diets have been linked to lower immunity. Children and pregnant women are especially vulnerable. Vegan babies are 20 percent more likely to be iron-deficient than children of normal weight, and vegans over age 70 are 50 percent more likely to be iron-deficient than non-vegans.
How Much Iron Do Vegans Need?
When you eat red meat, your body produces more vitamin B12, which is needed to make red blood cells, red blood cells absorb iron and convert it to hemoglobin. Once red blood cells are made, your body breaks them down into their component parts and uses small amounts of non-heme iron for tissues. That leaves only heme iron in the blood to be used by cells.
The health effect of iron deficiency depends on how much iron is missing from your diet. However, studies show that most vegans need to take in between 25% to 50% more iron than other vegetarians and vegans. Women need more iron than men, and vegans need more iron than people who eat meat, based on the assumption that women’s diets are more iron-rich than men’s.
A general guide to how much iron vegans need for their age can be found in the TLC Diet. A woman of any age who eats plant-based meals 2-3 times per day (and eats some fish) needs 400 mg per day to meet her basic needs. A veg woman who eats more often (or less), such as a woman in her sixties or seventies, needs 600 mg of iron per day to meet her needs.
One other factor to take into account is that vegetarians may not absorb iron as easily as omnivores. Once in the body, iron is distributed among the cells by diffusion. The body of an omnivore can absorb iron very quickly, which may help vegetarians to absorb more iron. Thus, vegetarians need to eat more iron to meet their needs.
Iron Deficiency
Iron deficiency is a condition in which your body doesn't have enough iron, particularly in your red blood cells. Symptoms include shortness of breath, fatigue, weakness, dizziness, and tiredness. In people who eat a diet low in iron, anemia is the most common form of iron deficiency. Treatment usually involves taking supplements.
Over time, the body builds up the iron in your blood. The goal is to have at least 75% of the recommended amount. It's normal to have to increase your iron levels every six to 12 months. In addition to diet, supplements may be necessary. Most people who don't get enough iron get just one of the symptoms. But you may have two or more of them.
Vegans may get an iron deficiency by eating too little iron-rich foods or not consuming enough iron supplements. This deficiency can be severe for vegans since they lack the healthy balance of vitamins and minerals provided by meat. Another possible health effect of a lack of iron in the diet is anemia.
Anemia is a general term for the deficiency of hemoglobin in the blood. Hemoglobin is an iron-containing protein in red blood cells. In anemia, the body has trouble transporting oxygen throughout the body. When oxygen cannot reach your tissues, they do not function properly, and there are signs of reduced oxygen in your tissues and excessive amounts of waste products in your blood.
The Importance Of Iron In Your Diet
According to the International Journal of Epidemiology, a high-quality diet high in fiber, fruit, and vegetables is correlated with a lower risk of iron deficiency. The U.S. Food and Drug Administration advises women over age 18 to consume 12.5 mg of iron daily to get the 40 milligrams of iron needed to maintain good iron status. If you are deficient, you may need to take iron supplements.
Vegans may need additional iron to meet the higher requirements of iron intake for optimal health. What are the benefits of iron supplements? Iron supplements are an effective way to get the added intake of iron needed to support normal growth and development. But they may not be necessary for vegans, who do not get enough from plant foods.
Iron plays an essential role in maintaining normal bodily functions. As a mineral, it binds oxygen, which is necessary for every bodily function. Without enough iron, there will be a shortage of oxygen, with serious consequences. The body’s red blood cells transport oxygen throughout the body.
Without iron, your body cannot adequately transport and release oxygen. The process in which the hemoglobin takes in iron is known as heme binding. Heme-binding is the only way that heme can be absorbed into the body. The hemoglobin then allows other molecules to enter the red blood cells and carry out heme’s function. A lack of iron can impair this process, resulting in iron deficiency anemia.
Too Little Or Too Much Iron
Iron deficiency can cause fatigue, weakness, dark urine, hair loss and dry skin. These symptoms may disappear after you eat iron-rich food. Iron deficiency also makes your immune system weaker. This increases the risk of getting sick. This can cause diarrhea, anemia (low red blood cell count), a bad cough and pneumonia. If you have kidney disease or take certain medications, you need to talk to your doctor before consuming iron-rich foods.
The American Association of Clinical Endocrinologists (AACE) published an article on iron deficiency and diabetes in 2006. They found that vegans who follow a healthy lifestyle can prevent and even reverse type 2 diabetes, depending on what they eat. Eating a diet rich in fruits, vegetables, and lean proteins lowers your risk of type 2 diabetes.
The recommended daily allowance of iron for healthy people is 55 mg per day. The general rule is that if you haven't had a blood test recently, then you need more iron than if you have had a recent blood test. You can find information about iron levels in the most recent blood test and make your own assessment of your current level of iron.
If you don't have a blood test handy, and can't remember when you last had one, you should talk to your doctor. Most people can tolerate slightly less than the recommended daily allowance of iron. This is about 20 to 30 milligrams per day. Some people have higher iron stores and might need to take more than this. If you are concerned about the amount of iron in your diet, then you should talk to your doctor or a dietician.
Fortified Breakfast Cereals
The best breakfast options are fortified cereals, which have added iron. Look for the nutrition facts for food groups on the back of the package. Fermented foods are also an excellent source of iron. Like other fermentable foods, they contain enzymes to break down the food, and active bacterial cultures, which aid in the digestion process.
Most people are familiar with soybeans and their various uses in foods, but did you know that a small quantity of soybeans is fortified with iron, zinc and B vitamins? Red yeast rice is another high-iron, fermented food. It’s easy to find in Asian grocery stores or supermarkets. Another way to get iron from grains is by eating sourdough bread made from fermented milk. It’s called sourdough starter.
Blackstrap Molasses
Commercially available blackstrap molasses contains sugar, corn syrup solids, sulphites and gluten. It also contains casein and dairy products. So how is it a good source of iron? The high sugar content will not be as harmful as a large amount of milk solids. Corn syrup solids can be beneficial for some people.
They contain sorbitol and mannitol, which can help lower your blood sugar. But corn syrup solids are almost entirely metabolized in the small intestine. So a big, concentrated amount of corn syrup solids may be more harmful than beneficial. Mangoes Blackstrap molasses will not be as effective for vegans as it is for people who eat meat because of the low iron content. But it will still be a good source.
Green Leafy Vegetables
Vegans are often advised to take a daily vitamin C supplement. Vitamin C is essential for the metabolism of iron. Eating raw or lightly cooked green leafy vegetables provides a lot of vitamin C. Leafy greens are the best sources of vitamin C. Berries and some citrus fruits are also good sources. Vitamins C and E also are vital for a healthy immune system, which protects you from infections. Most fruits are full of iron. Grass-fed beef offers more iron than pork, which can contain additives. But if you want to get iron from these foods, you must thoroughly cook or drain them.
Dried Beans
A staple of the vegan diet, beans are a good source of non-heme iron. Not only are they delicious when stewed or sauteed, they are also packed with protein. Black beans, garbanzo beans, kidney beans, pinto beans, chickpeas, lentils, split peas, and lima beans are good choices.
Commonly consumed in the United States, chickpeas are low in fat and calories. They are also high in iron, calcium, and protein. Add a cup of chickpeas to your favourite salad or vegetarian stew. Legumes—beans, peas, and lentils—also provide a good source of iron. Several kinds of legumes are great additions to omelets, stir fry or salad. Beans also make excellent chilli or fried beans.
Whole Grains
Whole grains are made from two or more parts of the grain. Non-white parts of the grains like the bran and germ are soaked or sprouted to make the whole grains easier to digest. Whole grains also contain high levels of vitamins and minerals, like iron, that your body needs. According to Mark Sisson, author of “The Primal Diet,” whole grains may even be more beneficial for vegans.
Non-whole grains, like enriched flour, often contain unhealthy added ingredients like ingredients to prevent illness, antibiotics, growth hormones and artificial ingredients. These ingredients are often found in red rice flour, puffed wheat flour, and wheat gluten. Whole grains contain protein from the brain that is often not absorbed in wheat and refined grains, but that is absorbed in oats and wheat germ.
Enriched Rice Or Pasta
Take non-heme iron supplements as the most commonly recommended source of this mineral. Take it in addition to non-heme iron-rich food sources such as legumes, dark green leafy vegetables, dried fruits, nuts and seeds, and wholegrain cereals and bread. Non-heme iron is found in some fortified breakfast cereals, potato products, cereal bars and soy milk. The Food and Drug Administration (FDA) issued guidelines in 2016 recommending fortification of some foods with non-heme iron.
Conclusion
Meat-free eating may not be as difficult as you think. There are numerous plant-based options, including beans, lentils, peas, nuts, seeds, whole grains, sweet potatoes, broccoli, carrots, bell peppers, sweet potatoes, beets, spinach, kale, avocados, tempeh, tofu, sausages, tempeh sausages, seitan, seitan bacon, tempeh jerky, tempeh fish, tempeh patties, sprouted soybeans, walnuts, and tomatoes, to name a few.
Vegans also eat substantial amounts of green leafy vegetables, berries, fruits, and mushrooms. Additionally, there are plenty of excellent meat substitutes available, like seitan, cashews, tofu, bison, lamb, and tempeh.
Beans and lentils are the easiest sources of plant-based protein. It's easy to have a vegetarian meal without meat. A vegetarian diet can be even more varied. Choose beans, lentils, nuts, seeds, whole grains, and legumes. Fruits and vegetables are also good sources of protein.
